1921] Smiley: Flora of the Sierra Nevada of California 317 



Specimens examined. Camp Agassiz, near Glen Alpine, Tahoe, 

 Dudley, June 28, 1900; Pedlar, Amador County, 7,000 feet, Hansen 

 516 ; Cathedral trail to Mt. Tallac, Tahoe, 7,000 feet, Smiley 219. 



This species is common in the Sierra in the Yellow Pine belt; its 

 inclusion here is of doubtful propriety, the only reason being that it 

 is likely to be found in the Pinus ponderosa var. Jeffreyi division of 

 the Canadian zone. 



2. GREENEOCHAKIS 



1. Greeneocharis circmnscissa Rydb. (Bull. Torr. Bot. Club, vol. 

 35, p. 677. 1909), a small annual widely dispersed in the Great Basin 

 region from British Columbia to Lower California and growing 

 typically in the Upper Sonoran life-zone, appears to have a variant 

 in the boreal region of the Sierra, which was collected by Culbertson 

 (B 4243) on the trail to Mt. Whitney and has been described as the 

 var. Tiispida by Macbride. 120 The specimen has not been seen by me.
